Abstract

The invention discloses a multi-domain horizontal alignment type liquid crystal display panel, which comprises an active element array substrate, an opposite substrate and a liquid crystal layer arranged between them, wherein the opposite substrate has a common electrode layer. The active device array substrate includes a substrate, a plurality of scanning lines, a plurality of data lines and a plurality of pixel units, wherein the scanning lines and the data lines are arranged on the substrate and define a plurality of L-shaped pixel areas on the substrate. The pixel units are respectively arranged on the L-shaped pixel area. Each pixel unit includes an active element, a pixel electrode, a plurality of first and a plurality of second alignment members, wherein the pixel electrode is electrically connected to the active element. The first and second alignment members are disposed on the pixel electrode, wherein the first alignment member is perpendicular to the second alignment member, and the first alignment member forms an included angle of 45 degrees with the horizontal direction.

Description

technical field [0001] The present invention relates to a liquid crystal display panel (liquid crystal display panel, LCD panel), and in particular to a multi-domain horizontal alignment (MHA) liquid crystal display panel. Background technique [0002] Thin film transistor liquid crystal display has gradually become the mainstream of the market due to its superior characteristics such as high image quality, good space utilization efficiency, low power consumption, and no radiation. Currently, the performance requirements of the market for liquid crystal displays are towards high contrast (High Contrast Ratio), fast response and wide viewing angle. Currently, there are technologies capable of meeting the requirement of wide viewing angles, such as Multi-domain Vertical Alignment (MVA) TFT-LCDs, Multi-domain Horizontal Alignment (MHA) TFT-LCDs, and the like. [0003] figure 1 It is a top view of an existing thin film transistor array substrate used in a multi-domain horizont...
